Application filed January 30, 1915. Serial No. 5,271.

To all 1071 am it may concern I Be it known that I, WILLIAM B. Tacos, acitizen of the United States, residing at citaunton, in the county ofvlacoupin and State of Illinois, have invented certain new and usefulImprovements in Means for Air choring tovepipes, of which the followingis aspecifleation, reference being had to the accompanying drawings.

My invention relates to smoke stacks or stove pipes, and particularly tomeans whereby a smoke stack or stove pipe may be anchored to a fluewall.

The primary object of my invention is the provision of a very simple andeffective form of stove pipe section so constructed that it may bereadily interlocked or anchored to a flue wall, provision being madewhereby a joint of the pipe section may be closed and made smoke-tight.I

A further object of the invention is to so construct a stove pipesection of this character that the sections may be readily nested fortransportation and readily applied to or removed from engagement with aflue wall.

@ther objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings wherein- Figure1 is a longitudinal sectional view of a smoke stack or stove pipeillustrated as projecting from a wall and interlocked therewith; Fig. 2is a fragmentary rear elevation of a portion of the stack or pipeshowing the joint therein; Fig. 3 is a section on the line 3-3 of Fig.1; Fig. A is a perspective view of the joint cap; and Fig.

5 is a perspective view of a portion of one of the pipe sections.

All of the sections of the smoke stack or pipe have the form illustratedin Fig. 5, that is, each section has a cylindrical body 2 with radiallyprojecting oppositely disposed confronting flanges 8, these flangesbeing provided along their entire extent with belt holes 4:, these boltholes being spaced a predetermined distance apart as for instance, abouttwo inches. Normally, there is suffi cient resiliency in each of thepipe sections that the flanges 3 are held separated from each other butthe flanges are brought into smoke tight contact by means of the boltswhich pass through the flanges and by means of a joint cap 5 illustratedin Fig. 4. This joint cap is U-shaped in form and fits over the flanges8 and clamps these flanges together and the joint cap is formed with aplurality of perforations 6, these perforatrons being spaced apart fromeach other the same distance that the perforations 4: are. After the caphas been placed upon the oint, the bolts 7 are passed through theperforations as illustrated in Fig. 3, and the flanges pressed tightlyin engagement with each other. It is to be noted that the joint caps,while they have a length equal to each section of the pipe, are disposedupon the joint pipe sections in staggered relation so that when onesection of the pipe is inserted within the next adjacent section, thejoint cap will overlap both of these sections.

In order to provide means whereby a stove pipe or stack may be anchoredto a wall, as for instance a flue wall, I provide a section A which hasits flanges 3 cut away as at 8 to an extent equal to the thickness ofthe wall 13, these flanges 8 being bent inward so as to overlap. A smallportion of the seam 3 is left at the end of the pipe so as to engageupon the rear face of the flue wall and prevent the joints from pullingout of the flue. Before the flanges 3 of this section of the pipe arebolted, the pipe section can be rolled together somewhat so as to makeit smaller in diameter when inserted within the flue opening and allowit to spring out to its proper diameter. This causes the flanges 3" tolock in the flue. After this is done and the next pipe section isinserted in the end of the section A, the bolts 7 may be inserted andthe pipe sections bolted into position.

As illustrated, the section 0 which follows the section A is shown as anelbow. In the case of the elbow section, the seam or joint formed by theflanges C is to be disposed so that it will not be readily observableand will extend upward and be hidden by the body of the stack or pipe,as shown in Fig. 1.

It will be seen that my construction permits the ready engagement of astove pipe or smoke stack with a wall and further it will be seen thatthe section A which is formed for engagement with the wall may beinitially formed with the outstanding flanges and the inturned flangesbut without these flanges being joined to each other and thus the pipesections may be readily nested for transportation.

Having described my invention, what I claim is 1. The combination with awall, of a pipe cut away for a ness of the Wall, the pipe section beinginradially projecting flanges, the flanges being distance equalto thethick:

serted through an opening in said wall, the wall engaging the cutawayportion to thereby interlock the pipe section to the wall, and meansengaging said outstanding flanges and holding them abutted' against eachother, to close the pipe'section.

2. The combination with a Wall, of a pipe section projecting therefrom,said section having radially projecting flanges, the

' flanges being cut away for a distance equal to the thickness of thewall, the pipe section being inserted'through an opening in said wall,and said wall engaging in the cut away portion to thereby interlock thepipe section to the wall, and a cap fitting over that portion of theflange joint exterior to the wall and engaging the flanges;

3. As an article of manufacture, a hollow 7 pipe section longitudinallysplit and provided with outwardly. projecting longitudinally extendingflanges, said flanges being cut away at one point to provide an openingadapted to permit said flangesto embrace a Wall, said; outwardlyprojecting flanges being adapted to be engaged with each other;

4. As an article of manufacture, a pipe section composed ofryieldingmaterial, said section having a cylindrical body longitudinally splitand formed with radially projecting confronting flanges, certainopposite portions of the flangesbeing separated from the remainingportions of the flanges, said separated portions being bent at an angleto the plane of the outstanding portionsof the flanges and overlappingeach other, the portions of the flanges so bent having a Width equal toa wall into'which the section is to be inserted to thereby form aninterlocking notch in theoutstanding flanges adapted to embrace saidWall, said outstanding flanges being adapted to be closed against eachother to thereby close the pipe section.

In testimony whereof I hereunto aflix my signature in the presence ofwitnesses.
